Possible Switching Modes Of The 8311 - Burkert 8311 Manuel Utilisateur

.6 Possible switching modes of the 8311

Hysteresis mode
The change of state occurs when a threshold is detected
(increasing pressure: high threshold (OHI) to be detected,
decreasing pressure: low threshold (OLO) to be detected)

The delay (dEL) is set for the both switching
thresholds. The switching only occurs when
either threshold value (OHi - OLO) is excee-
ded for a duration higher than the dEL delay.
